Abstract

An image collaboration system conducts resolution independent image collaboration among a host computer and participating client computers. The subject of the image collaboration involves at least one source image. The source image is transformed into a hierarchical representation, such that each level of the hierarchical representation is sufficient to reconstruct the source image at a given resolution. The host computer displays, at a first resolution, an image based on one or more of the source images. To conduct the resolution independent image collaboration, the host computer generates a resolution independent description of the image, which describes the first display image relative to the source image, and broadcasts the resolution independent description of the image to the participating clients. In response, the participating clients generate an image from the resolution independent description of the image at the host computer at a resolution sufficient for display at the participating clients. Resolution independent image collaboration for use in a medical informatics system is also disclosed.
